If you chant this Hare Kṛṣṇa mantra, the first result will be that you will understand your real, constitutional position, for which many great mystics, sages and saints are meditating, "What I am?" That, I mean to say, procedure of spiritual realization will be the first installment, your profit. You'll understand that ahaṁ brahmāsmi, "I am not matter, I am spirit soul."
And as it is stated in the Bhagavad-gītā, as soon as one is self-realized, that is called brahma-bhūtaḥ. Ahaṁ brahmāsmi: "I am not this body, I am spirit soul. I am part and parcel of the Absolute Truth." This realization is called Brahman realization. And as soon as you come to the platform of Brahman realization, then the result will be brahma-bhūtaḥ prasannātmā (BG 18.54).
You'll be joyful. You'll be free of all anxieties. Brahma-bhūtaḥ prasannātmā. That is the sign. It is not that simply . . . I may advertise that I am self-realized, but my behavior will show whether I am self-realized or not. Everything is stated in the Vedic literature, that a brahma-bhūtaḥ person, a self-realized person, the symptom of the self-realized person is that he is joyful.
